I have two MDA Varios 2, one with 1350 Battery, one with 1500 battery. Phone 1 had the 1500 Battery, Phone 2 had the 1350 Battery set, both a had a sim card, Phone 1 from T-Mobile (3 G enabled) the other from Dubai (Said 3G but I doubt it was correct as they do not have that even in Dubai). Both had internet connections off, (ie no 24hrs gprs connection etc, connect on demand)
After 14 hours of 0 use on both phones, the Dubai phone with the 1500 battery had 100% power, the other had 40%>>WOW
Great I thought, must be the new battery! So I reversed the test, put the 1500 AM battery in the UK 3G T-mobile one, and the 1350 in the Dubai sim one.
And guess what, everything reversed, the dubai simmed phone was up around 100% and the T-Mobile was down around 50%.
Conclusion:
So the difference between the batteries is non existant, but the SIM/ 3G sim connection is a killer.
How do I turn off 3g on my T-mobile without losing all GPRS?? Any Help It must be the sim??

Has anyone experienced the drain on the battery with 3g, as my Battery does not last a night when using 3g, but I was in the 3g free zone (gsm only) during the weekend and the battery lasted the whole weekend.
My battery will drain 50% quicker when in a 3G area, Somtimes I set the device to use standard GSM frequencies to keep the battery alive.
I'd guess it is the switching that causes the battery drain (at least this is the case with most 3G phones ) if you spend a lot of time (i.e. your workplace or home) on a "borderline" area your battery will get sapped pretty quickly
Setting the phone to use one band and stick to it (practically , this has to be GSM / 2g for a constant signal ) is the best soloution , until such time as blanket 3G coverage
Pain in the neck really

same with me, i need to plug in the charger every ~40 hours. i live i 3G area, also using web'n'walk often...
I get way less than this. I have push email enabled, which keeps the internet connected constantly. However in my house I only get one-bar of 3g - often flipping to full four-bar GPRS
I only get about 24 hours between charges!
I have got serious 3G battery draining problems too.
How do I set up the TyTN to only use 2G ??
Thanks,
Martin
- Tap the phone icon on the top menu bar;
- Select settings;
- Select band;
- For select your network type: select GSM
- For select your GSM/UMTS band: select Auto
This setting works great for me on Cingular on an old AT&T SIM in and around Washington, DC. THe battery life is also very good. Also remember as posted on another thread in this forum that even if you do not have 3G yet in your area, if you get EDGE, you will see faster speeds on the TyTN. The TyTN has a new feature called Extended TBF Release which improves the overall throuput.
Hi all,
Made an experiment with 100% battery and connected with agilemessenger on a UMTS network. It only took 3 hours to drain my 100% battery to zero.
And I also tried to connect agilemessenger on a EDGE/GPRS network, after 12 hours of connection, I still have 50% of battery remaining.
I REALLY wonder does a UMTS network draw battery that bad compare to a GPRS/EDGE network literally?
Can anyone comment about this?
Thanks
Mark
Same situation here with UMTS, how do you choose to connect between normal EDGE and UMTS network ? I am currently in HK and using service from CSL1010.
Cheers

my experiment showed that in 3G mode, my Vario II is able to last no more that 2 days on full battery, while in 2G mode this time doubles up to almost 4 days.
hi all,
Can anyone tell me how can I turn on/off HSDPA?
As HSDPA drains my battery like hell compare to a normal UMTS network.
What I need to do is to turn off HSDPA when I need to remain connected for a long period of time such as agilemessenger. HSDPA can drain my battery from 100% to zero within less than 3 hours. I strongly believe a normal UMTS (without HSDPA) can last the battery a lot longer.
Pls tell me if you have any suggestions or correct me if my thought is wrong.

Hello,
You can do it with fit4cat hermes tweaker.
I attach this ZIP file.
Good use
can anyone comment on whether this indeeds help with battery life? I need my data on all the time so any help on that front would be cool. And if so how much does it conserve?
thanks
NOOOO ... dont use the fit4cat update for this .. it's not supposed to be used on production devices that have their HSDPA enabled already ..
best option will be to apply the reg hack to enable the phone band settings on the Cingular 8525 (Cingular wisely decided to disable this, look on the wiki for this reg update) .. and select GSM to back down to GSM network ...
Depending on your usage of UMTS the device might get hot .. so using the GSM bands will definitely be helpful if the 8525 is getting hot ..
i had also created a cab for the band selection

Thanks for your suggestions.
If you have read my thread clearly, I am not intending to downgrade my network back to GSM.
I am intending to disable HSDPA only, I still want my UMTS connection.

Thanks for your attachment. I have successfully installed the tweaker, however, failed to run it.
Other than this tweaker, any other method to switch off HSDPA??
Again, I still need my UMTS, just want to turn of HSDPA (3.5G) only.
Mark
my bad ... didnt understand your first email properly ... And personally, I havent seen any such hacks to disable just HSDPA (UMTS still working) so far for the TyTN ... Maybe pof or Sleuth255 know something ...
Question tho - How do you know that HSDPA drains more battery than just UMTS?

Made a simple experiment.
As I have tried between 2 carrier SIM cards.
Carrier A supports HSDPA, it drains my battery from 100% to zero in less than 2.5 hours with MSN or agile Messenger connected.
Carrier B supports only normal UMTS, my battery managed to survive around 8 to 10 hours with messenger connected as well.
I think this can pretty much prove that HSDPA drains the battery much worse compare to a UMTS network.
Mark
IMO that does not necessarily mean that HSDPA network sucks up more power than UMTS .. it's possible that Carrier A might have a really bad data network where your handset is timing out while trying to make a data connection and is constantly re-trying .. this could be a real drain on the battery ...
Anyways .. just my 2c ..
I have the opposite problem. I get much better battery life at home on the HSPDA network than I do at work on a UMTS network...
I charged my phone Friday night and used it for maybe 30 minutes on Saturday/Sunday (voice) and an hour and a half of streaming radio on Saturday and was still at 30% early this (Monday) morning.
A lot of folks get similar battery life with just HSDPA/UMTS usage...
In idle mode it is always UMTS signaling ( even you see HS ) hence if you are not in a data session the battery usage is the same
In dedicated mode, Uplink is always UMTS but the downlink is HS. It is normal that the battery consumption increases with higher bandwidth. Notice that if you remain iddle for say t sec ( set by the operator) the system will downgrade you to UMTS.

this could be caused by carrier A's tower being farther away, causing the phone to transmit at a higher power level. the data transmissions will make the power draw even higher, and you'll see extreme differences in battery life between the two.
hsdpa is slightly less power efficient than umts for a number of reasons (processor overhead, different transmit power and channel management protocols) but i seriously doubt it's an 80% reduction in battery life. i can't see many manufacturers buying into hsdpa technology if such incredibly poor power management was a side effect.
I just switched over from an Artemis which had really great battery life. 2-3 standby is not uncommon with heavy usage (calls and GPRS). The Trinity however is dire! My day starts at 0800 and by 1800 battery is down to 20%, this is with network set to automatic, which means 3G most of the time.
Anyone having poor battery performance on their Trinity or do I have a bad battery?
Processor makes a big difference, I found my 200mhz Wizard lasted a lot longer on heavy usage than my Trinity.
With that said, I also find that 3G is a real battery hog at least on the Trinity. Not sure if it's just a case of the Trinity or all 3G devices but when I'm connected to a UTMS network my phone dies a lot quicker, so much so that for most of my usage, I keep it forced on GSM

It always has been that way with UMTS (3G) phones. My SE K610i lasted much longer with UMTS switched off. Just try to turn it off on the trinity.

I loaded this little app. called BandSwitch. It makes my Trinity stay on GSM Edge unless I really need the speed of 3G. It turns the data off at night to save even more battery. This program has dramatically increased my Trinity's battery life. http://commmgrpro.com/_wsn/page3.html
I also have HSDPA turned off all together because my network won't allow a call to be connected while HSDPA is active. You can change that setting with HTweakC found at the Hermes Wiki.
What battery improvements have you seen?
This is just my opinion when I use this phone, Xperia XA.
I have just bought it for 5 days. At night, cell standby eats my battery about 40%. So I check in Setting -> About phone -> Status -> SIM status and you know what I see: SIM card I use for calls is EDGE and another one I use for mobile data is HSPA (I didn't turn on mobile data). I guess calls SIM should be GSM (EDGE is for data too, not only text and call) and data SIM should be GSM too (or at least is EDGE or GPRS), because I didn't turn on mobile data so I think that is problem that eat my battery.
Both EDGE and HSPA (or HSPA+) is for data, it consume more battery than GSM.
Another surprise is when I take 1 SIM out my phone, I turn on my phone, switch it to LTE(prefered)/WCDMA/GSM. Check again at same place (SIM status) - I didn't turn on data, too. And I saw, my SIM card, with no data, running at LTE (my signal is 0). So I came up with this, Xperia XA choose wrong mobile type network, make it drain fast.
I just want you guy who use XA, do same thing that I do and check if it wrong.
Thank you you guy.
UPDATE: Check my conclusion downthere.
Hey, after a night with out SIM 2, SIM 1 run at EDGE, I only lost 3% (from 99% to 96%). That really good.
Sorry, I can't upload screenshot. Internet at my country is down.
In Battery (Setting):
Cell standby: 40%.
Phone idle: 44%.
Conclusion
Way to fix battery drain problem by cell standby (for Dual SIM XA - mine is F3116):
At night, deactivate Data SIM, switch another to GSM only and sleep. I only lost 3% after 8 hours.
When you wake up, activate Data SIM and enjoy the day.
Hope it help you guy.
